According to MLB.com's T.R. Sullivan, the Rangers "may explore interest" in Aaron Miles, recently released by the Cincinnati Reds.
Miles could fill in for the injured Ian Kinsler, though he'd be unlikely to approach anything like Kinsler's production.
For instance, Miles has 16 career home runs in 2,423 plate appearances. Kinsler hit 31 home runs in the 2009 season alone.
Sullivan says that Miles would likely begin at Triple-A.
